Driver's License Categories
Length, Width, and Height
A centre-axle trailer combination must not exceed 18.75 metres in total length. The combined external lengths of the load spaces must not exceed 15.65 metres, and the distance from the front of the towing vehicle’s load space to the rear of the trailer’s load space must not exceed 16.40 metres.
Exemptions may be granted for vehicles exceeding standard dimensions:
- Maximum width: 2.60 metres
- Maximum height: 4.20 metres
Maximum Permissible Mass
Passenger car trailers (category O1–O2) are towed vehicles designed for transporting passengers, goods, or for recreational purposes. They are classified based on total mass as follows:
- Category O1 (light trailer): Total mass does not exceed 825 kg.
- Category O2: Total mass exceeds 825 kg but does not exceed 3,500 kg.
Braking Requirements
Trailers are categorized based on braking systems:
- O1 (light trailer): With a maximum gross vehicle weight of 825 kg, brakes are not mandatory.
- O2: Trailers with a total mass over 825 kg but not exceeding 3,500 kg must be equipped with mandatory brakes, including an anti-lock braking system (ABS).
Drawbar Weight
A general guideline is that the drawbar weight should be around 10% of the trailer’s total weight, typically between 30–100 kg.
For unbraked trailers, the drawbar weight should be less than 5% of the trailer’s total weight.
Incorrect drawbar weight can negatively impact driving stability and pose a serious safety risk on the road.
All trailers manufactured by Bestnet Oy have been type-tested.

Registration
To register a trailer, the following requirements must be met:
- Proof of ownership must be provided.

- If the registered owner is different from the manufacturer, a certificate of transfer of ownership must be submitted.
